Led Zeppelin III

Led Zeppelin focused more on their acoustic side for their third album. More diverse than its predecessors,  it even featured a banjo on one song (Gallows Pole).  But that’s not to say that the album didn’t have its moments of bombast that Zeppelin was known for.  Many critics panned the album, probably because they were expecting something heavier. That didn’t stop it from topping the billboard charts and going double platinum in sales.
